A molecularly imprinting polymer (MIP) was synthesized for Basic Blue 3 dye and applied to wastewater the adsorption of a target template. The MIPs were by bulk polymerization using methacrylic acid (MAA) ethylene glycol dimethacrylate (EGDMA). (BB-3), 2,2'-azobisisobutyronitrile (AIBN) methanol used as functional monomer, cross linker, template, initiator porogenic solvent, respectively, while non-imprinting polymers (NIP) same procedure but without template molecules. contact time 25 min...
Synthesis of a monolith architectured silica-anchored graphene oxide composite and its adsorption demonstration for the removal chromium( vi ) iii ).
Electrochromism refers to the persistent and reversible change in color by applying an electric field. The phenomenon involves insertion extraction of electrons ions within active material. There is a keen interest electrochromic (EC) materials, since they exhibit wide range potential applications. In recent years, transition-metal oxides have been widely investigated as EC materials due their low power requirement, high coloration efficiency, memory effect under open-circuit condition....
A silica capillary of 50 μm internal diameter and 500 mm length (416 effective length) was chemically modified with 4‐(trifluoromethoxy) phenyl isocyanate in the presence dibutyl tin dichloride as catalyst. Sodium diethyl dithiocarbamate reacted terminal halogen bound ligand to incorporate initiator moiety, situ polymerization performed using a monomer mixture styrene, N ‐phenylacrylamide, methacrylic acid. The resultant open tubular column immobilized copolymer layer used for separation...
Ground porous silica monolith particles with an average particle size of 2.34 μm and large pores (363 Å) exhibiting excellent chromatographic performance have been synthesized on a relatively scale by sophisticated sol-gel procedure. The distribution was rather broad, the d(0.1)/d(0.9) ratio 0.14. resultant were chemically modified chlorodimethyloctadecylsilane end-capped mixture hexamethyldisilazane chlorotrimethylsilane. Very good separation efficiency (185,000/m) resolution achieved when...
Recently, the development of visible-light-responsive catalysts for photodegradation organic pollutants has captured attention researchers globally. The ineffectiveness and high costs associated with conventional methods techniques used abatement water pollution have forced to develop effective low-cost innovative this purpose. Photocatalysis is considered an protocol Therefore, study was conducted Bi2O3-NiO heterojunction as a photocatalyst degradation methyl orange. Ni(NO3)2∙6H2O (Fluka)...
A ligand with a terminal halogen (4‐chloromethylphenyl isocyanate) was chemically bound on the inner surface of pretreated silica capillary 50 μm internal diameter and 58 cm total effective length in presence dibutyl tin dichloride as catalyst through isocyanate‐hydroxyl reaction. Attachment initiator (sodium diethyl dithiocarbamate) to carried out followed by situ polymerization. Reversible addition‐fragmentation chain transfer polymerization used for immobilization N...
Lesions and stable secondary structures in mRNA severely impact the translation efficiency, causing ribosome stalling collisions. Prokaryotic ribosomal proteins Rps3, Rps4 Rps5, located entry tunnel, form helicase center unwind during translation. However, mechanism underlying detection of lesions on translating is unclear. We used Cryo-EM, biochemical assays, knockdown experiments to investigate apurinic/apyrimidinic (AP) endoribonuclease activity bacterial ribosomes AP-site containing...
Columns packed with silica-based bonded phases have been used in reversed-phase liquid chromatography because of their high porosity, large surface area, compatibility different solvents, mechanical stability, ease modification, and economic feasibility.
